Definitions

  • the invention relates to a roller drive unit according to the preamble of claim 1.
  • roller drive units for the carriage of freight in one Airplane cargo space are in a variety of embodiments, for example known from DE 41 02 424 or US 3,712,454.
  • a roller drive unit for the carriage of freight in an aircraft cargo bay with a propulsion engine working with one the longitudinal axis is coupled to a rotatable drive pulley, which has a core and a mounted thereon coat having an outer surface comprising, which with a bottom a freight item in frictional engagement for its carriage can be brought is, solved in that the jacket has at least one boundary layer that is formed and between at least one inner cladding layer and an outer cladding layer is attached, that on the one hand, the cladding layers firmly connected to each other and on the other hand, a spread a tear is limited by the one in the other cladding layer.
  • An essential point of the invention is therefore that a substantially repeatedly and inevitably occurring crack does not lead to a complete break the entire lateral surface, but only to a separation of Sections may result. It thus according to the present invention, the boundary layer no reinforcing layer in the true sense, since neither the mantle surface which frictionally engages the ones to be conveyed Freight comes, nor the stability of the layer as a whole or its stop on the core are affected by the boundary layer.
  • the jacket layers are preferably concentric with the outer surface of the drive roller designed so that a symmetrical structure arises.
  • the lining for the drive roller that is, the entire jacket as a band, comprising a boundary layer and form a cladding layer (or integer multiple thereof) to wind on a core and finally to form concentric to the core (zu polymerize or vulcanize).
  • the boundary layer preferably has openings, pores or the like Openings through which material of the adjacent cladding layers can get in direct contact with each other.
  • the openings / pores must be designed so large that just this stop the Coat layers is guaranteed to each other and yet the "crack limiting" Effect of the boundary layer is maintained.
  • the boundary layer can be formed in a variety of forms. Especially easy is the formation of the boundary layer as a tissue with a relatively coarse Structure such that said material connection of the cladding layers ensured among each other. In particular, this is a single-ply Tissue relatively easy.
  • the outages described at the outset of sufficient elastic-soft sheath material to a tolerable level can limit be accomplished in that to the boundary layers in the direction the longitudinal axis and / or radially to the longitudinal axis extending boundary walls provided in the material layers and are formed such that Regions of the cladding layers firmly connected by the boundary walls are.
  • Side sufficiently elastic jacket material to use in which cracking by special types of stress (cuts or the like) practically unavoidable, by the provision of boundary walls (boundary layers) to "catch" the occurring cracks or break out jacket material areas to limit.
  • cladding layers of rubber or the like vulcanizable material or made of polymerizing material are preferably the cladding layers of rubber or the like vulcanizable material or made of polymerizing material, as it is known.
  • the cladding layers are preferably made from prepolymerized or prepolymerized Rubber manufactured as surface elements, wound on the core (with the boundary layers between cladding layers) and then in one Vulcanized mold (hot). It is possible to wrap in multiple layers, so that a spiral arrangement of the boundary layer is formed. Important this is, of course, that the outer circumference in the end absolutely cylindrical and formed coaxially with the core and in this form by the subsequent vulcanization / polymerization is fixed.
  • a drive roller rotatable about a longitudinal axis 1 comprises 10 a core 11 and a mounted thereon, in particular vulcanized Sheath 20 made of rubber.
  • An outer surface 21 of the jacket 20 arrives during transport of freight items with their underside with frictional contact, like this is known from the prior art.
  • the jacket 20 comprises in the embodiment mentioned here an innermost Cladding layer 28, which is vulcanized directly onto the core 11.
  • an inner boundary layer 23 On the innermost The lateral surface is an inner boundary layer 23, on the turn an inner boundary layer Jacket layer 27 is located.
  • On the inner cladding layer 27 is another Boundary layer 22, on which an outer cladding layer 26 is located, whose 11 facing away from the core surface forms the outer surface 21.
  • the cladding layers 26, 27, 28 and 29 are as this has been attempted in Figure 2 to illustrate, interconnected, that the material of the respective cladding layers 26 to 29 merges into one another. This is done in a conventional manner by vulcanizing rubber material or polymerizing out of plastic material.
  • boundary layers 22 to 24th are boundary layers 22 to 24th arranged in the example shown here from a coarse, burlap or pluck-like woven fabric which is woven from threads 20.
  • this layer it is also possible to use this layer in a different technology It is always important to obtain a structure that - As shown in Figure 1 - has a plurality of openings 33, so that the Sheath layers 26 to 29 can be firmly connected to each other.
  • the boundary layers 22 to 24 thus form no reinforcement of the jacket material in the true sense of the word, they are used exclusively for hiking To prevent cracks from the outer surface 21 in the direction of the core 11 and to limit.
  • As a material for the threads 20 may textile material, but in particular Also carbon fiber material can be used. It is also possible monofilthough To use grating structures as boundary layers 22 to 24.
  • boundary surfaces 25 are adjacent to the boundary layers 22 to 24 also in the radial direction and in the circumferential direction to the core 11 and whose longitudinal axis 1 arranged boundary surfaces 25 are provided so that bounded areas 32, as indicated in Figure 3 by the broken lines, arise.
  • boundary surfaces 25 is thus a spread of cracks and fractures parallel to the outer surface 21, so both in the circumferential direction as well as in the direction of the longitudinal axis 1 limited to the bounded areas 32. The detachment of larger surface areas is thus effectively prevented.
